Slide up multiple lines in Ticket Design - Header

Hello, just wondering if anyone else has had problems with blank lines in addresses when  trying to slide up more than one line? Our address layout is set up like this:

Salutation 1

Street 1

Street 2

Town

State

Postcode

When only one of these fields are blank then slide up works as expected and moves all the fields below up a line.  However, when a second field is blank the subsequent fields are only moving up one space instead of two which is leaving a  blank space in the address eg:

Salutation 1

Street 1

Town

Postcode

It's not the end of the world just wondering if anyone else has found this and what they have done to resolve it.

Thanks in advance
